Single low-side driver for fast N-channel switching
The Texas Instruments TPS2817DBVR is a single-channel low-side gate driver designed to drive N-channel MOSFETs. It delivers 2A peak source and sink current with typical rise and fall times of 14ns each, making it suitable for high-frequency switching applications such as DC-DC converters, motor drives, and power-supply stages where fast gate charge and discharge are needed. The non-inverting input accepts logic levels with VIL of 1V and VIH of 4V, so it interfaces directly with 3.3V or 5V PWM controllers without external level shifting. Supply range is 4V to 14V, covering common bias rails for industrial and automotive auxiliary supplies.
Package and temperature grade
Housed in a SOT-23-5 (SC-74A) surface-mount package, the TPS2817DBVR occupies minimal board area and suits dense layouts. The ROHS3 compliance simplifies lead-free assembly compliance.
Sourcing and lifecycle
For dual-sourcing consideration, the LM5106MM/NOPB is a half-bridge driver with 1.2A switching current and 8V supply minimum, but it drives two MOSFETs in a half-bridge configuration and is not a pin-compatible drop-in.
